Abstract

The utility model adopts thermal tubes to realize a great amount of heat transmission and constant temperature control, which provides an environment with comparatively constant temperature for chemical reaction, ensures a controllable and predictable reaction and effectively improves product quality and yield. A plurality of communicated thermal tubes are arranged to form a thermal tube heat transmitter; one ends of the thermal tubes are connected together in a capillary or a case way; connection tubes are arranged at the upper end and the lower end of the arranged thermal tube to communicate two adjacent thermal tubes; a small connection tube is adopted at the other end of the arranged thermal tube to communicate two adjacent thermal tubes; the outer wall of the thermal tube is provided with fins and the thermal tube consists of a metal tube and internal terminal work fluid; the metal tube is vacuumized and the two ends thereof are closed; the internal terminal thereof is filled with a certain amount of liquid which is regulated according to demand; the fins on the outer wall of the thermal tube promotes the heat transmission effect; proper liquid is added from an external terminal according to requirements for heating and condensing. A heat exchanger which adopts the thermal tube can be multivariate or single.

Description

Constant temperature fluidized bed furnace chemical reaction equipment

Technical field

The utility model relates to a kind of device that is used for liquid, gas at constant temperature fluidized bed furnace chemical reaction.

Background technology

The reaction of fluidized bed furnace generally is to adopt the mode of directly heating or indirect to carry out, and temperature controlling mainly realizes that by forced circulation or other modes the fluctuation ratio of temperature is bigger, and the quality of product is had considerable influence.

Summary of the invention

The purpose of this utility model is to adopt the big heat transmission of Heat Pipes, and realization temperature thermostatic control, making chemical reaction be in the environment of relative constant temperature carries out, that can guarantee to react controls with measurable, can effectively improve the quality and the output of product, its scheme is: the heat pipe that adopts many connections, arrange and constitute heat pipe heat spreader, one end of heat pipe adopts capillary or casing mode to link into an integrated entity, on the heat pipe of arranging, the lower end, with tube connector adjacent two heat pipes are communicated with, and heat pipe one end of arranging, with little tube connector adjacent two heat pipes are communicated with again, the outer wall of heat pipe can be equipped with fin, heat pipe is made up of metal tube and inner working medium, vacuumize in the metal tube, closed at both ends, the liquid with some is filled in the inner, this liquid can be adjusted as required, and the fin of heat pipe outer wall can increase heat-transfer effect, the liquid that the outer end adds can adopt suitable liquid as required, liquid composition that be used to heat and condensation adopts heat pipe exchanger, and heat exchanger can be the unit or polynary.

The specific embodiment

See also shown in the accompanying drawing 1, adopt the heat pipe 1 of many connections, arrange and constitute heat pipe heat spreader, one end of heat pipe adopts capillary or casing mode to link into an integrated entity, with tube connector 3 adjacent two heat pipes 1 are communicated with at heat pipe 1 upper and lower end of arranging, and, with little tube connector 4 adjacent two heat pipes 1 being communicated with again at heat pipe 1 one ends of arranging, the outer wall of heat pipe 1 can be equipped with fin 2; See also accompanying drawing 2, shown in 3, heat absorption (or heat release) constant temperature fluidized bed furnace is in reactor, be provided with heat pipe heat spreader with communication apparatus, when the reaction of (being the upper end during heat release) generally is in fluidized state in its lower end, temperature wishes it is low more good more (then desired temperature is high more good more during heat release), the a large amount of heats that produce can be delivered to the top of heat pipe effectively, the characteristics of heat pipe transmission heat are, heat is in transmittance process, can lose hardly, therefore, the heat that reaction produces can be brought to the top of heat pipe in the shortest time, heat pipe top is to be in the liquid of a boiling, and its heat is taken away by liquid evaporation rapidly, and the working medium of taking away behind the heat is just just got back to the heat pipe hypomere along inside pipe wall, participate in evaporation once more, a large amount of heats is taken away, and the process of this evaporative condenser is continuous, and the reaction heat of heat pipe hypomere (the heat release state is supply heat) just is delivered to rapidly in the liquid (reactant) on heat pipe top by heat pipe.

Adopt present technique can produce all kinds of have pressure and stress-free chemical reaction equipments, can be used for all kinds of boiling reactors, also applicable to all kinds of fractionation apparatus, can accurately control cut point, improve the fractionation quality, therefore can be widely used in the petrochemical industry fractionating device, all kinds of gases and liquid reactor, each class I liquid I is to the reaction of liquid; Since the temperature of the temperature of condensation segment and evaporator section can be by response the situation of inside and outside working medium adjust, the adaptation zone of its temperature is very wide.
